Strange issue with my car?

About 2 weeks ago while sitting at a light, my car started to idle really rough. After the light changed, I started to go and the car hesitated and chugged foward until I got to about 2000rpm. After I got to the next light, the car was running fine like nothing was wrong. A couple days later it did it again, but this time it did it for about 15 min. After that, it didn't do it again for a week. Could my opti be going out. The car only has 63k on it. I changed the o2 about a month ago, and I put new plugs and wires in it about a year ago.

It's got a new coil, so I can rule that out. But I will check the ICM.

Fuel pump could be headed south.

BTW....great looking car man. I love that color but I thought it was only available in 1994. Did you repaint?

If you haven't done it in a while, throw in a new fuel filter before going after the pump. Check the pressure with a gauge though and be sure that you get near 43psi with the vacuum line off the FPR and also see if pressure holds for a while once the car is shut off.

Thanks man! No, didn't repaint her. It's the factory color. I need to get a new pic up, the car has gunmetal TTM's now.

Try cleaning the MAF. A bad or dirty MAF will make your car run like crap.

Had a very similar issue with my car. I couldnt figure it out for the life of me (no check engine light or anything) I ended up taking a shot in the dark and changed the 02 sensors and it fixed my problem.

I didn't get to it today. I'm gonna try tommorrow. I also put new o2's in the car about a month ago, so that can't be the problem. If I have to I'll take it to the dealer and get it scanned.
